Gateway GX7022E won't boot.

My computer won't start up. I hear the fan and the hard drive and one indicator light is on the one on the actual button is not coming on and nothing happens on the monitor. The computer has been cutting off and overheating for about a month, we had it tested and they found no problem with any of the hardware and now it won't boot at all. If anyone could help I'd be grateful because I love this computer and don't want to replace it.

Well, it could be any component going bad, in this order: power supply, video card, memory, motherboard. You can try known working video, power and memory if you'd like, but it is probably the motherboard in this particular case. If you look at the capacitors on the mobo, you'll probably find that at least some of them are bulging at the top and/or leaking. the only thing to do if this is the case is to try and replace the bad caps - but this is VERY difficult, even for an expert.

Watch the fan on the power supply when you turn it on does it run or jiggle and stop. if it jiggles and stop then its likely the supply needs replaced . cheap fix.if the fan runs then its on the board and more steps must be done.

Test your PSU power supply unit or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle of restarting or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive power and data cables IDE SATA

the leads from yourMOTHERBOARD TO YOUR HARD DRIVEmake sure they have a secure dust free connections and are not faulty or just replace them they could be faultymake sure all leads that are attached to your dvd\cd floppy drives have secure connections and are not faulty or just replace them they could be faulty computers need power and data to travel through every working device to continue its cycle and have an end so any faulty leads will end up with a computer erroreven something as small as a faulty electrical or fan lead can cause you problems

motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail

check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working

also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered incheck you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat Thermal compound is a sticky paste that is placed directly onto the CPU. Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink. hope this helps

Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

How long is shortly? If it runs and brings up the Windows Desktop and
you are allowed to work for 10 minutes or longer then it shuts down,
most likely the laptop is overheating. One way to tell if it is
overheating is to immediately try to turn it back on after it shuts off.
If it will not boot back up, it's overheating. If you let it sit and
cool off for a while, then try to boot it back up and it does it
successfully, it's overheating.Causes of Overheating:1) Dust all inside
the computer. Fans clogged with dust, dust around the vents.2) Fan not
working 3) The Thermal Past around the CPU has dried up or is too thin
the keep the unit cool.When you plug in the power cord is there any
lightswhatsoever on the laptop, where the plug goes in or on the AC
Adapter of thepower cord?

When you press the power button do you
hear fans running, hard drive spinning,lights on the computer, hear any
beeps or lights constantly blinking, hear theDvD/CD drive click and the
light on the drawer of the DvD/CD turn on for asecond or two? If so the
laptop is trying to boot or may have booted, butthe screen is not
showing for some reason.

Beep tones and blinking lights tells the
technicians what is going on with thelaptop and why it is not booting.
Most times it's a motherboard issuewhen you hear beeps or blinking
lights continuous.

Do you hear the harddrive start up? When you push the power button (or switch on the back) do the lights go out? If you hear fan running and hard drive start up then the computer itself might be on but the monitor isn't. Check the power to the monitor, the connection between monitor and computer to make sure they are all on and connected.

If you don' t hear the fan running then you have other problems. Any blinking lights would indicate something is getting power. I'm assuming the computer was working before the power button was pushed... If the monitor is actually working, you could hook up another monitor to check too then you have other problems but need more info to know what that could be.

would need to know the answer to the above questions as well as if it was working before, what was done, what changed between it working and this problem. Also what age the machine etc.

Step 4
If
you can hear the computer's fan or hard-disk drive, or if you can see
indicator lights on the main unit but the monitor stays dark, make sure
that the monitor is connected to a working power source, that it's
turned on and that it's securely connected to the computer via the
video cable.

Step 5
If
the monitor and computer have power but the computer displays a
"Non-system disk or disk error" message, check to make sure you didn't
leave a disk in the A: drive. If you did, eject it and restart the
computer.

the gateway hang indicates to things either a bios problem or a failing hard drive,sometimes when hard drives start getting old they take a while to spin up and/or has difficulty finding the boot sector,you also have corrupt files which would indicate a failing hard drive.

Try just restarting your computer the hard drive will already be warmed and spun up so the Gateway screen may pass faster.

Try running this prog to diagnose a failing hard drive,it will run in the background so just uninstall it your drives fine.

is there a reset button on the power supply. if so try that. you might have accidently disconnected the hard drive cable. unplug AC and check all the connectors around the area where you installed the video card. make sure everthings connected. then before u close the case re connect the AC and check visually if the power is on and if everthings running.
